Lallana, who turns 25 in May, has impressed since being made Saints captain in the summer for the club's first campaign back in the Premier League, and scored in Saturday's 2-0 win over Reading.

He follows Kelvin Davis, Rickie Lambert, Morgan Schneiderlin, Jason Puncheon and Luke Shaw in committing his long-term future to the club, in a deal which will keep him at St Mary's until the summer of 2018.
